摘　　要：低温低浊微污染水由于其水质的特殊性,一直是饮用水处理中面临的难题。以天津某水厂水源水为试验水质,在前期直接过滤试验研究基础上,采用高锰酸钾、臭氧为氧化剂进行预氧化以强化直接过滤处理低温低浊水的效果。结果表明,2种预氧化技术均能不同程度提高对水中有机污染物的去除效率,其中臭氧预氧化对水中有机微污染物去除效果提升较大,对UV254和CODMn的去除率均能达到57%,较单独直接过滤处理分别提高了42%和40%,比高锰酸钾预氧化工艺提高了32%和19%;臭氧预氧化-直接过滤工艺更适合于对该种水质的处理。Because of the particularity of its water quality,low temperature and low turbidity micro-polluted water had continuously been the problem of drinking water treatment.The study used source water of one water plant in Tianjin as the water quality,and according to the experimental investigation of direct filter in former tests,using ozone and potassium permanganate as the oxidizers in order to enhance the effect of enhanced direct filtration in low temperature and low turbidity micro-polluted water treatment.The result showed,both the two oxidation technologies can improve the removal rate of organic pollutants on different levels,and the removal rate of micro organic pollutants further improved by ozone pre-oxidation,both the UV254removal rate and the CODMnremoval rate can reach to 57%,compared with direct filter,they have added 42% and 40%,respectively,and compared with potassium permanganate pre-oxidation,they had added 32% and 19%,respectively.And it also showed that ozone pre-oxidation direct filtration technologywas more suitable for the treatment of the test water.
